Quantas is diode pumped, air-cooled, Q-switched laser designed for wide range of applications that require low pulse repetition rate and high peak power pulses (Q1D model produces ~5 MW peak power). Due good thermal properties of Nd:YAG crystal Q1-1064 can operate at higher pulse repetition rates in comparison to Q1-1053. Laser can produce up to 30 mJ at 20 Hz repetition rate or up to 10 mJ at 50 Hz repetition rate. Typical applications are Light Induced Breakdown Spectroscopy (LIBS), Light Induced Fluorescence Spectroscopy (LIF), laser ablation and remote sensing. Less than 8 ns pulse duration allows efficient fundamental wavelength conversion to higher harmonics with shortest wavelength available of 213 nm. Wavelength extensions into infrared range are available by request. Quantas is completely air cooled laser due its excellent wall-plug efficiency. Liquids are not used for heat transfer, as result, maintenance associated with regular replacements of cooling liquid and/or cleaning of cooling system is not required. Low jitter triggering pulses for user equipment are available with up to 300 μs lead in internal triggering mode. If required, laser pulsing can be externally triggered from delay generator, allowing operation in single-shot or variable pulse repetition modes. Laser controller has Ethernet interface for convenient monitoring and control from personal computer.
